Thus, it is very important and necessary to monitor and diagnose the running condition and the faults of the steam turboset for the safe and normal running of the electric power system. In this paper, the Internet/Intranet based remote condition monitoring and fault diagnosis scheme is proposed. The corresponding technique and methods are discussed in detail.

The proposed scheme can guarantee real-time data acquisition and on-line condition analysis simultaneously. And especially, the remote condition monitoring and fault diagnosis can be implemented effectively. The developed system has been installed in a power plant of China. And the plant has obtained great economic benefits from it. Introduction The electric power industry is the fundamental industry for the national economy. Thus, the running condition of the electric power system has a great influence on the performance and development of the national economy. The steam turboset is the key equipment of the electric power system. Apparently, it is very important and necessary to monitor and diagnose the running condition and faults of the steam turboset for the safe and normal running of the electric power system especially because of the steam turboset evolving in the direction of high-parameter, high-efficiency, high-power and high-automation [1-2]. In addition, to improve the maintenance efficiency and service efficiency of the steam turboset, the running condition based maintenance strategy has been proposed to complement or even replace the traditional scheduled maintenance strategy. And obviously, the condition monitoring and fault diagnosis of the steam turboset is the premise for such reformation of the maintenance strategy. Just because of above two points, the importance and the necessity of the condition monitoring and fault diagnosis of the steam turboset has obtained more and more recognition from the plants and the research society. And the power plants have put forward more and more urgent demand for the condition monitoring and fault diagnosis technique for the steam turboset [3]. Fortunately, with the development of the relevant techniques, such as electric and electronic technique, computer software and hardware technique, signal processing technique and artificial intelligence technique, the mechanical fault diagnosis technique has obtained great progress during last half century. For the rotating machinery, such as the steam turboset, many effective diagnosis methods and strategies have been developed. And the mechanism of the frequent faults has become clearer and clearer.

2 366 Damage Assessment of Structures VI execution of the condition monitoring and fault diagnosis for the steam turboset. Actually, many systems have been developed for the steam turboset and obtained successful application in the power plants [1, 3, 4, 5, 6]. However, with the proposition and execution of the condition based maintenance strategy, the enterprises put forward new demands for the condition monitoring and fault diagnosis that above systems can not meet very well mainly in the following aspects [7, 8, 9]: Most systems are not mature from a production point of view and their reliability and stability are not satisfactory and need improvement. The function of the system seems a little simple. And the configuration of the function is not flexible. In addition, man-machine interface is not friendly. Thus, the operation of the system is not easy for the ordinary operating worker. The construction and the data format of the system lack openness. And thus, it is always difficult to connect the system to the production management network of the plant. This situation limits the usage of the system. The diagnosis mode and reasoning strategy of the diagnosis sub-system are always unitary. And thus the reliability and accuracy of the diagnosis result are not satisfactory. The function of Internet based remote monitoring and diagnosis is still at an initial stage. For most systems, so called Internet based remote monitoring and diagnosis just means data remote delivery and communication. With respect to above problems, in this paper, an Internet/Intranet based remote condition monitoring and fault diagnosis scheme is proposed. The corresponding technique and methods are discussed in detail. And a real application system is developed for the 300MW steam turboset. In this scheme, the system is built on the Internet/Intranet and the Client/Server construction and Web/Server model are adopted to guarantee real implementation of remote condition monitoring and fault diagnosis. The system includes four subsystems: Data sampling subsystem, real-time monitoring sub, data and Web server subsystem and fault analysis and diagnosis subsystem. Each subsystem is responsible for corresponding task. And such distributive system construction can guarantee the on-line ability and real time ability of the system simultaneously. The paper is organized as follows: In section 2, a general scheme design of the system is discussed, including function determination, hardware platform and software environment, etc. Section 3 gives a description of the various subsystems in detail. Section 4 introduces the real application system for the 300MW steam turboset. Finally, Section 5 summarizes the conclusions of the research in this paper. General Schematic Design of System Design Principle and Function Determination. Being different from the ordinary instruments and meters, through practical and effective function determination and open construction, the condition monitoring and fault diagnosis system realizes multiple dimensional monitoring of the running condition, finds out the trend of the running condition, diagnoses the extent, the cause and the location of the faults and finally serves the equipment management and the condition based maintenance strategy. Thus, the scheme design and function determination of the system will follow the following principles: Openness in the construction and compatibility in the hardware and software for the future extension of the system and connecting to other systems. Internet/Intranet based system construction for the remote monitoring and diagnosis. Reliability and stability in the hardware and software for long-term on-line monitoring. Combining automatic diagnosis and manual diagnosis for the practicability and flexibility of the diagnosis function.

In the system, Figure and image recognition techniques and neural network techniques are utilized to intelligently recognize and automatically acquire the running symptoms of the set. Based on knowledge rules and the fault object frame, the system generates a fault tree for inference automatically or manually. The system combines rule-based knowledge and model-based knowledge and uses the former to diagnose the occurrence of the fault and the latter the location and extent of the fault. Based on neural networks and genetic algorithms, a diagnosis case learning unit is developed to perfect and update the knowledge base. The block diagram of the diagnosis expert system is shown in fig.7. Application System for 300MW Steam Turboset Based on the above scheme, an application system of condition monitoring and fault diagnosis is developed for the 300MW steam turboset of Guangdong Huangpu Electric Power Plant in China. The application system was installed in the plant in March last year. And up to now, the system works very well and provides much valuable information of the turboset to the plant, which is very helpful for the plant to efficiently use, manage and maintain this key equipment. Especially, the system guarantees the safe running of the set and avoids serious accidents. Because of such benefits, the system obtains more and more recognition and welcome from the plant and was awarded the
